Description

Technical Field

[0001] This utility model relates to the field of speed-regulating multi-purpose oscillators, and in particular to a speed-regulating multi-purpose oscillator. Background Technology

[0002] As a common biochemical instrument, the variable speed multi-purpose oscillator plays an indispensable role in scientific research, education, and production departments such as plants, biology, microorganisms, biological products, genetics, virology, medicine, and environmental protection. It is mainly used for culturing and preparing biological samples.

[0003] In existing technologies, variable-speed multi-purpose shakers are typically equipped with positioning nets for fixing experimental containers. Operators place various experimental containers, such as test tubes, centrifuge tubes, and conical flasks, in the corresponding positions on the positioning nets. The positioning nets, relying on their own elastic mesh structure, initially fix the containers. Together with components such as the shaking disc, this ensures that the experimental containers remain relatively stable during the shaker's operation, thereby ensuring the normal conduct of the shaking experiment.

[0004] However, the positioning net of existing variable-speed multi-purpose oscillators is often fixed in height during use. Since the heights of containers used in experiments vary considerably, ranging from short test tubes to tall flasks, a fixed-height positioning net cannot flexibly adapt to containers of different heights. When using shorter containers, the positioning net cannot effectively constrain the container from a suitable position, relying solely on the lower support of the oscillating disc, making the container prone to swaying or even tipping over during oscillation. Conversely, when using taller containers, the positioning net can cause unreasonable pressure on the top of the container, leading to damage to top components (such as broken test tube caps or ruptured flask necks) or seal failure (such as the test tube stopper being squeezed out). This affects the smooth progress of the experiment and the accuracy of the results, while also increasing the risk of damage to the experimental container. Therefore, a variable-speed multi-purpose oscillator is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a speed-adjustable multi-purpose oscillator, which aims to improve the problem that the positioning net of the existing speed-adjustable multi-purpose oscillator cannot be adapted to experimental containers of different heights.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a speed-adjustable multi-purpose oscillator, including an oscillator base 1, an auxiliary fixing device 3 at the bottom of the oscillator base 1 for maintaining the stability of the oscillator as a whole under operation or under external impact, an oscillator positioning net 4 above the oscillator base 1, and an adjustment device 2 inside the oscillator positioning net 4 for adjusting the height of the oscillator positioning net 4.

[0035] The adjusting device 2 includes an adjusting frame 201. The outer surface of the adjusting frame 201 is slidably connected to the oscillator positioning net 4. Therefore, when the limiting state of the insertion rod 204 is released, the height of the oscillator positioning net 4 can be directly pulled to adjust it. A limiting block 203 is slidably connected to the inner surface of the adjusting frame 201 to limit the movement range of the control rod 202. The control rod 202 is fixedly connected to the inner surface of the limiting block 203. An inner shaft 207 is fixedly connected to the inner surface of the adjusting frame 201. An outer shaft 205 is rotatably connected to the outer arc surface, and a connecting block 206 is fixedly connected to the outer arc surface of the outer shaft 205. A rectangular sliding groove is opened on the inner surface of the connecting block 206 to accommodate the end of the insertion rod 204 to move inside it. The end of the connecting block 206 away from the outer shaft 205 contacts the insertion rod 204. The insertion rod 204 cannot be dislodged from the through holes on both sides of the adjusting frame 201 during the movement, and always maintains a sliding connection with the adjusting frame 201. A toggle block 208 is fixedly connected to the back of the outer shaft 205.

[0036] Reference Figure 3 , Figure 4 as well as Figure 6The inner surface of the oscillator positioning net 4 has multiple sets of through rectangular grooves to accommodate the adjustment frame 201 inside. The front and rear sides of the rectangular grooves of the oscillator positioning net 4 have staggered slots, so that when the insertion rod 204 is inserted into the slot, the oscillator positioning net 4 cannot be pulled up or down. Rectangular through holes are provided on both the left and right sides of the adjustment frame 201 to accommodate the insertion rod 204 extending out. A through hole is provided at the upper end of the adjustment frame 201 to accommodate the movement of the control rod 202 in the vertical plane. The limiting block 203 is larger than the diameter of the through hole at the upper end of the adjustment frame 201, thus preventing it from detaching from the adjustment frame 201. A... The toothed protrusions prevent the connecting block 206 from moving. A through hole is provided at the center of the inner surface of the outer shaft 205 to accommodate the inner shaft 207. The outer arc surface of the inner shaft 207 is elastically connected to the outer shaft 205 by a spiral spring. Therefore, when the control rod 202 is not squeezed by external force, the spiral spring can push the outer shaft 205 to reverse through its own elastic force and push the control rod 202 upward. The outer surface of the insertion rod 204 is slidably connected to the adjusting frame 201. The size of the insertion rod 204 is the same as the size of the internal slot of the oscillator positioning net 4, so that it can be inserted into the internal slot of the oscillator positioning net 4. The upper surface of the toggle block 208 is in contact with the control rod 202.

[0037] Reference Figure 1 as well as Figure 5 The auxiliary fixing device 3 includes an air intake rod 302. The outer surface of the air intake rod 302 is slidably connected to the oscillator base 1. A limit block 301 is fixedly connected to the upper end of the air intake rod 302 to limit the movement range of the air intake rod 302. A return spring 304 is fixedly connected to the outer surface of the limit block 301. A vacuum suction cup 303 is fixedly connected to the lower surface of the oscillator base 1.

[0038] The air intake rod 302 is sealed to the vibrator base 1, thus preventing external air from entering the vacuum suction cup 303 when the air intake rod 302 is not connected to the vacuum suction cup 303. The inner surface of the air intake rod 302 is hollow, and the lower surface of the air intake rod 302 has an arc-shaped through hole, so that it can be connected to the vacuum suction cup 303 below when it is pressed into the vibrator base 1. The lower surface of the vibrator base 1 has a through hole and is connected to the vacuum suction cup 303. The center of the inner surface of the vacuum suction cup 303 has a through hole. The outer surface of the limiting block 301 is elastically connected to the vibrator base 1 by a spring, which is used to push the air intake rod 302 outward when it is not pressed.

[0039] Working principle: When using this device, the control lever 202 needs to be pressed according to the actual height of the experimental container. At this time, the control lever 202 will press the actuating block 208 under the pressed state, and the actuating block 208 will drive the outer shaft 205 to rotate. During the rotation, the outer shaft 205 will drive the upper and lower sets of insert rods 204 to retract into the adjustment frame 201 through the connecting block 206. During the retraction process, the end of the insert rod 204 near the connecting block 206 will slide, so that there will be no motion interference, thereby releasing the position limitation of the oscillator positioning net 4. At this time, the oscillator positioning net 4 can be pulled up and down according to the actual experimental container specifications. When it is adjusted to the specified height, the control lever 202 is released. At this time, the elastic force of the spiral spring will push the outer shaft 205 to rotate in the opposite direction and push out the insert rods 204 at both ends again, so that they are inserted into the oscillator positioning net 4 and their position is limited.

[0040] In addition, before using the oscillator, it needs to be placed in a designated area. At this time, press down on the oscillator base 1, so that the vacuum suction cup 303 below is squeezed to squeeze out the air inside, and the pressure difference between the inside and outside helps to stabilize the oscillator on the plane. When the position of the oscillator needs to be adjusted, press the air inlet rods 302 on both sides into the oscillator base 1. At this time, the through hole below the air inlet rod 302 will be aligned with the through hole in the center of the vacuum suction cup 303, so that outside air can enter the vacuum suction cup 303, thereby eliminating the pressure difference between the inside and outside and releasing the auxiliary fixing state. At this time, release the air inlet rod 302, and the return spring 304 will push the air inlet rod 302 outward again, thereby releasing the gas conduction state between the vacuum suction cup and the air inlet rod 302, and allowing the vacuum suction cup 302 to reposition the oscillator.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
